Thanks Dave, very well explained.
Simple ?, will the basic peep sight be much better than the tangent sight currently on the CZ455 Ultra Lux. It will have about a 6" longer lenghth site.
If my eyes were as good as when I was younger, the tangent sights would be wonderful. Love the distance movements of the tangent CZ sights.
Will the "Skinner sights"which I was looking at online,  be better than tangent sights.? My eyes are good at distance, but I am up to 1.75-2.0 reading glasses.
Hate to get away from the original sights but they are blurry to me. I can shoot about 3-4" groups at 50 yards, much below the guns capabilities.
My CZ 452 Ultra Lux Super Exclusive with a scope, I can shoot a Quarter size group at 75 yards and I am far from a target shooting pro.
Thanks Brian
